Specification of Letters Patent.

PRUETT, 0F COVINGTON, KENTUCKY.

- Patented June 11,1918.

Application filed September 6, 1917. Serial N 0. 189,990.

To all whom 2'25 may concern: I

Be it known that I, TRUMAN C. PRUETT, a citizen of the United States, and a resident of Covington, in the county of Kenton and State of Kentucky, have invented new and useful Improvements in Cuttin Devices, of which the following is a speci cation.

Iy invention is an improvement in cutting devices, and has for its object to provide a device of the character specified, especially adapted for cutting the wrappers from newspapers, periodicals, ackages and the like, wherein a shoe is provlded, adapted to run beneath the wrapper and to be at-' tached to a cutting blade which will cut the wrapper as the shoe moves beneath the same.

In the drawings:

Figure l is a top plan view of the improved device;

Fig. 2 is a side view with away;

Fig. 3 is a side view, showing the blade reversed;

Fig. 4 is a perspective view showing the device attached to the blade of a pen-knife; Fig. 5 is a side view of the blade shown in Figs. 1, 2 and 3;

Fig. 6 is a top plan view of the shoe; and

ig. 7 is a rear view of the shoe.

In the embodiment of the invention shown in Figs. 1 to 3, inclusive, the blade 1 is substantially triangular, having its hypotenuse side sharpened, as shown, and the blade has a shank 2 which is received in a split in one end of a handle 3. The handle at opposite sides of the split may be compressed on to the shank, or it may be riveted to the shank as may be found advisable. The shoe 4 is approximately rectangular, the sides, however, converging slightly toward one end and the said end is beveled, as shown at 5, to permit its easy insertion beneath the wrapper.

The shoe has an extension 6 at its rear, and from this extension a pair of clamping arms 7 extends upwardly, the said arms being connected to the extension by outwardly curved portions 8 which provide for some degree of adjustment and resiliency. These arms 7 are adapted to extend upon opposite sides of the blade 1, and a set screw 9 is journaled in one arm and has threaded engagement with the other, to permit the arms to be clamped upon the table.

At the rear of the extension and beyond the arm an upwardly extending forked lug parts broken 10 is provided, which is adapted to engage the shank of the blade in Figs. 1 and 2, as shown, to properly position the blade with respect to the shoe. It will be noticed from an inspection of Figs. 2 and 3 that the blade 1 has a notch 11 at the base and at the side remote from the cutting edge, and when the blade is in use as a cutter this notch is engaged between the arms of the fork of the lug 10. The shoe has a. guard 12 for engaging the point of the blade to protect the same, so that the said point will not stick into the article wrapped.

In use, the parts are arranged as shown in Fig. 2, the cutting edge of the blade being upward, and the lug l0 engaging the notch 11. \Vhen now the point 5 of the shoe is inserted between the wrapper and the article wrapped, it will be evident that by pushing the shoe and the blade longitudinally of the article the wrapper will be slit, without any possibility of injuring the article Wrapped.

hen not in use the parts may be arranged as shown in Fig. 3, that is, with the cutting edge of the blade adjacent to the shoe and resting on the shoe and extension. It will be noted that the shoe is slightly curved transversely, as shown more particularly in Fig. 1, in order to fit the contour of the package.

As shown in Fig. 4 the device may be connected with the blade 13 of an ordinary penknife 14 by arranging the back of the blade in contact with the shoe and resting in the lug 10, the arms 7 being clamped over the blade, as shown.

It will be understood that the improved cutting device is also well adapted for cutting paper.

I claim:

1. A device of the character specified for attachment to a cutting blade, and comprising a shoe provided at its rear end with a reduced extension having upstanding arms adjacent to the shoe and adapted to embrace the blade, a set screw for clamping the arms on the blade, said extension having at its rear end an upstanding notched lu for engaging the blade for holding the lade inclined to the plane of the shoe, the shoe haviiligda protector or guard for the point of the 2. A device of the character specified for attachment to a. cutting blade, and comprising a shoe provided at its rear end with a reduced extension having upstanding arms adjacent to the shoe and adapted to embrace the blade, a set screw for clamping the arms on the blade, said extension having at its rear end an upstanding notched lug for engaging the blade for holding the blade inclined to the plane of the shoe.

. 3. Av device of the character specified for attachment to a cutting blade, and compris- Cepies of this patent may be obtained for five cents each, by addressing the ing a shoe provided at its rear end with upstanding anns adapted to embrace-the blade, a set; screw for; clamping the arms on the blade, said shoe having beyond the arms an upstanding notched lug for engaging the blade to hold the blade inclined to the plane of the shoe.
